Q71.If the mean deviation about median for the number 3, 5, 7, 2k, 12, 16, 21, 24 arranged in the ascending order, is 6 then the median is (1) 11. 5 (2) 10. 5 (3) 12 (4) 11
What This Question Tests
This question involves calculating the median of an ordered data set, then using the given mean deviation about the median to find the unknown value 'k' and finally the median itself.
Concepts Tested
Formulas Used
Median for even number of observations = (n/2 + (n/2+1)) / 2
Mean deviation about median = ฮฃ|xi - M| / n
